part of the general solution and runs off the tree and has 

 probably not had time to kill insect life. 



Dr. Britton : I should expect the results would be 

 much better if no rain came within two or three days, but it 

 is generally supposed that miscible oils kill the scale much 

 more quickly than lime and sulphur. There is one point 

 which should be borne in mind, and that is this : most of the 

 packages now contain directions for handling contents, but 

 the contents in each original package, whether to make a 

 single gallon or a barrel, should be mixed very thoroughly 

 before any is taken out or diluted with water. I have seen 

 injury caused to trees because the man having in charge the 

 work simply went and dipped out a vessel of liquid from off 

 the top of the barrel without stirring it. The quantity he 

 took would not mix with water, and the consequence was 

 that nearly every bud on the tree to which the liquid was 

 applied, was killed, and the tree did not put forth leaves 

 until along the latter part of June, and the buds were all 

 killed. There is where a great many people make the mis- 

 take and a great deal of injury is done. The contents of the 

 packages need to be thoroughly mixed and stirred before 

 being used and it needs to be noticed whether it mixes with 

 water or not. It is also said that some of the soluble oils 

 are placed in packages that the wood absorbs some of the 

 alkali, and so it is necessary to add something to it before 

 using. I believfe if the miscible oils are handled properly and 

 carefully, there need be no injury to any trees in Connecti- 

 cut. However, if a man has been spraying his peach orchard 

 with lime and sulphur and is satisfied with it, I should advise 

 him to continue its use. I believe it is such an excellent fun- 

 gicide that we should not lose sight of it in our great desire 

 to get something that is easy to apply. 



Mr. Farnsworth : I would like to ask Professor Jarvis 

 if he has made observations in regard to the fungicidal prop- 

 erties of the oil preparations. 



Professor Jarvis : Last year, in our experiments at 

 Middlefield, we sprayed about a thousand trees with oil. In 

 an adjoining lot there was another orchard which was
